Several outbursts of activity on Mount St Helens

There were several bright flashes clearly visible on the processed images from last night. It is clear that there were several landslides exposing fresh hot lava to the surface on both sides of the growing dome.

As reported yesterday, the lavadome has developed a number of large fractures along its length, which may lead to increased landslides and night time activity. A recent infra-red image from the USGS/CVO shows the fractures quite clearly.

Hey, there Darryl! Keep up the great work! I have been capturing most of the day and night images with webreaper, as you recommended! A great tool for keeping up with the eruption!

Yeah, several day time events too, with larger ash clouds yesterday. Looks like the more significant landslides are starting to occur, as predicted. The "whaleback" area is becoming more unstable as it has gotten steeper over time.
